Estimates for Durrmeyer-type exponential sampling series in Mellin-Orlicz spaces

Demonstratio Mathematica
This study examines Durrmeyer-type exponential sampling series to obtain a quantitative estimate by using the concept of the logarithmic modulus of smoothness defined with the help of a suitable modular functional on Mellin-Orlicz spaces.

Embeddings of Rearrangement Invariant Spaces That Are Not Strictly Singular

, 1999
. We give partial answers to the following conjecture: the natural embedding of a rearrangement invariant space E into L1 ([0; 1]) is strictly singular if and only if G does not embed into E continuously, where G is the closure of the simple functions in

Gradient estimates for a class of higher-order elliptic equations of p-growth over a nonsmooth domain

Advances in Nonlinear Analysis
This article is devoted to a global Calderón-Zygmund estimate in the framework of Lorentz spaces for the mm-order gradients of weak solution to a higher-order elliptic equation with pp-growth.

Extrapolation to Morrey Banach spaces on spaces of homogeneous type

Analysis and Geometry in Metric Spaces
This paper introduces the Morrey Banach spaces on spaces of homogeneous type. We establish the Rubio de Francia extrapolation theory for Morrey Banach spaces on spaces of homogeneous type.

Existence and uniqueness for double-phase Poisson equations with variable growth

Advances in Nonlinear Analysis
We study a class of nonlinear elliptic problems driven by a double-phase operator with variable exponents, arising in the modeling of heterogeneous materials undergoing phase transitions.
